Setup and Adjustments SETUP Proper setup and leveling of your power broom will increase the life of the brush and produces more efficient movement of material. Visually inspect the adjustments on the broom before each operating session and measure the adjustments once every 10 hours. Once the broom has been properly adjusted, a short operation period is recommended for break-in; approximately 15 minutes. After this break-in period repeat the leveling procedure to ensure that it is correct. Mounting instructions can be found either in an installation pamphlet or in the back of this manual. The following procedures must be followed in the prescribed order in order to be effective.

INSTALLATION (3-POINT)

• Remove any attachment from the 3-point arms.

• Position the tractor behind the broom.

• Insert 2 lower pins located on broom mount into ball sockets on tractors 3-point arms. (See illustration A)

• Attach tractors top link to broom with hitch pin.

• Lower the tractor arms until the desired height of approximately 14.63” to the bottom of the hitch frame is reached.

• Using the top link on the tractor, adjust in our out to level the hitch frame front to back. (Recheck the height of the hitch frame after making this adjustment).

• Adjust the broom pattern according to recommendations.

PATTERN ADJUSTMENT

• After the broom has been leveled, the last adjustment is to set the brush pattern. This adjustment is done by the use of the down limit chains.

• With the unit set-up on a flat level surface adjust the chains so that the broom has approximately 3” of contact from the front-most contact point to the rear-most contact point.

• Once this adjustment is set, it can be confirmed by running the unit for about 30 seconds in the down position while stationary. Stop the broom and back the unit away. The ‘cleaned’ portion of the surface should be 2”-4”.

General Operation PRE-STARTUP CHECKS

1) Visually inspect equipment and hardware to ensure that all parts are secure and all hardware is tightened and secure.

2) Check for oil leaks and loose hose connections using the proper method.

3) Visually check to ensure hydraulic hoses are connected to the correct tractor ports.

4) Inspect the bristle length to determine if replacement segments are needed.

OPERATION

• Caution!! Storage stands MUST be placed in the full upright position before moving else irreversible damage may occur.

• Sweep at a speed that is appropriate for the conditions and location.

• For heavy material such as gravel or stones, drive more slowly with high broom speed. For lighter material, drive faster with lower broom speed.

• Broom speed is usually controlled by adjusting engine RPM up or down.

• It may be necessary to increase broom pattern under some conditions. If the surface being swept is uneven and causes the broom to leave upswept patches, increase the pattern to compensate.

• If the material being swept is dried-on or difficult to remove such as mud or ice, it may be necessary to drive extremely slow to allow the broom to “scrub” the surface.

• Do NOT operate the broom in the raised position. While lifting the broom is acceptable to either clear an object or when reversing the prime mover, it is recommended that you shut off the broom for transporting.

Warning Fluid escaping under pressure can puncture the skin and cause serious injury.

Do not touch any hydraulic components until the tractor engine has been turned off and hydraulics disconnected. Before startup, check for loose hydraulic connections.

♦♦♦♦ Fluid accidentally injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.

♦♦♦♦ Make sure all hydraulic fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the system.

♦♦♦♦ Keep body and hands away from pinhole leaks or nozzles that eject high pressure hydraulic fluid.

♦♦♦♦ Use cardboard or paper, not your hands, to find hydraulic leaks.

♦♦♦♦ Safely relieve all pressure in the hydraulic system by placing the motion control pedals/levers in neutral and shutting off the engine before performing any work on the hydraulic system.

STORAGE

• Always store the broom in a supported position with the bristles off the ground. If the bristles are stored in a deformed position for extended periods of time the broom will become severely out of balance.

• Store the broom in a location out of the sun and weather to prevent premature failure of plastic bristles. Bristles can become brittle when subjected to sunlight or repeated temperature changes.

• Disconnect all electrical connections between the broom and tractor for extended storage to prevent battery drain.

• Properly clean the unit before storage and remove dirt, debris, salt, etc. to extend paint life.

• If the unit is power-washed, all lubrication points should be greased before storage.

Maintenance MAINTENANCE SCHEDULE

• Check adjustments – every 10 hours

• Grease bearings – every 10 hours

• Grease pivot points – every 50 hours

• Check and refill oil level – every 50 hours

• Replace oil filter – every 250 hours

• Replace hydraulic oil – annually

• Replace brush filler – as needed

• *Note* – Maintenance pertaining to oil and oil filter only refers to the independent hydraulic systems provided by M-B.

LUBRICATION

• Grease bearings and pivot points per the maintenance schedule using Chevron Ultra Duty II, Grade 2; or equivalent high-temp grease.

• There are minimum of (6) grease points on the unit; 1) pivot plate bushing, (2) oscillation plate, (1) oscillation pin, and (2) on the bearings.

• Use Chevron Rykon MV or Dexron-III/Mercon ATF or equivalent for M-B supplied independent hydraulic systems. If the oil is supplied by the prime mover, use the prime mover manufacturer’s recommended fluid.

Maintenance FILLER REPLACEMENT CORE REMOVAL • Lower broom until brush contacts the ground via

hydraulic lift cylinder or mechanical head anchor.

• Remove bolts attaching motor guard to the brush frame. Remove guard and set aside.

• Remove (2) ½” bolts attaching motor mount plate to the brush frame. Slide motor out of mating splined hub. Let motor hang on hoses.

• Remove hardware holding pillow block bearing to bottom of brush frame. Complete steps 2 thru 4 on both ends of core.

• Slide core out the front of broom.

BRUSH REMOVAL • Remove (3) ½” bolts attaching splined hub to end of

core. Remove hub and set aside.

• Remove (3) or (4) bolts attaching wafer retainer plate (end disc) to end of core. Set retainer and hardware aside.

• Slide spent filler and spacers off core and discard.

BRUSH INSTALLATION • Stand core in upright position and begin filling the

core by sliding an individual segment and spacer down the full length of the core starting with a poly segment. Note the location of the drive pin on the inside ring of each segment. Be sure to rotate each segment so the position of the pin is on a different side of the core with each segment being installed. This will help to insure proper balance on the core.

• Continue stacking the core in a segment-spacer, segment-spacer configuration until it is full ending with a segment. Always start and finish with a poly segment.

• The last segment should actually extend beyond the end of the core (Minimum ½”) so when the end disc is installed it compresses the filler onto the core when the bolts are tightened.

• Install end disc to the end of the core and secure with original bolts.

• Reinstall splined hub and bearing.

CORE INSTALLATION • Position refilled core in front of the broom head. Lift

the broom head high enough to place the filled core back into its original position. Once in place, lower broom head down onto the pillow block bearing at each end of the core.

• Reverse steps 2 – 4 from core removal section to complete reinstallation. Note: Apply grease or anti-seize to splines before installing hydraulic motors.

• Before placing machine back into service, adjust and test for proper amount of brush pattern. Excessive pattern can cause brush failure or premature wear.
